gemini TAP

The revolutionary machine to produce thread tools in one single clamping.

geminiTAP is the highly dynamic 6-axis CNC grinding machine for the serial production of threading tools with the capability of carrying out the complete processing of flutes, point, lead angle and thread forms in a single clamping. Maximum precision is guaranteed with a total of 6 CNC axes with linear and direct drive motor technology.

• Production: Taps, forming taps, thread mills

• Materials: HSS or carbide

• Diameter: 1 – 64 mm, any profile

• Spiral angle: No restriction

• Length: Up to 300 mm

Numerous accessories for the application spectrum and increased productivity:

  • 6-axis robot for workpiece loading with capacity for 2, 4, or 10 pallets
  • Dressing unit for dressing profiles and sharpening
  • Manual or hydraulic tailstock
  • Manual, hydraulic steady rest
  • Collet chucks, clamping mandrel
  • Coolant filtration system
  • Exhaust air filter
  • CO2 extinguishing system
